Heat capacity of free electrons at the degenerate-nondegenerate transition

In this Brief Report the heat capacity of an electron gas at the degenerate-nondegenerate transition is presented. The values are deduced from hot-carrier data of InSb with ≈ ${10}^{14}$ electrons/${\mathrm{cm}}^3$ determined by Maneval, Zylberstejn, and Budd.
